(CNN) – In calling for a broader, simplified tax code, Republican presidential candidate Mitt Romney said Friday that bigger businesses, in knowing how to utilize loopholes in the tax code, are "doing fine in many places" compared to small businesses.

"We've got to make it easier for small businesses," Romney told a crowd of about 300 people at a high-dollar fundraiser in Minnesota. "Big business is doing fine in many places -they get the loans they need, they can deal with all the regulation. They know how to find ways to get through the tax code, save money by putting various things in the places where there are low tax havens around the world for their businesses. But small business is getting crushed."
